5 of 5 New Upper Receiver February 19, 2021
: Nicholas Beresh from Houston, PA United States  
I was blown away by how fast my upper receiver showed up at my doorstep given how things are nowadays! After unpacking, I was impressed with the quality of the part that MAS has and can't wait to finish this build and get shooting. In addition, I had a question on rails and received a very quick response. Will definitely order again from these guys!
